Hydradrive HD-113 Constant Velocity Propeller Shaft Drive Kit with Thrust Bearing and Adapter

Hydradrive HD-113 Constant Velocity Propeller Shaft Drive Kit with Thrust Bearing and Adapter

The Hydradrive HD-113 Constant Velocity Propeller Shaft Drive Kit is designed for marine propulsion systems with engine power up to approximately 80 HP. The complete assembly combines a constant velocity (CV) drive shaft, a thrust bearing and a gearbox adapter to connect the marine gearbox to the propeller shaft.

The HD-113 is designed to transmit torque while accommodating angular misalignment in the propulsion shaft assembly. Its dedicated thrust bearing transfers propeller thrust directly to the hull through the mounting arrangement rather than through the engine and gearbox mounts.

The system is suitable for propeller shafts with diameters of 30, 35 and 40 mm.

Key Features

• Constant velocity drive: Homokinetic drive shaft for torque transmission between the gearbox and propeller shaft.
• Thrust bearing: Transfers propeller thrust to the hull through the dedicated bearing arrangement.
• High thrust capacity: Maximum specified propeller thrust of 10,500 N.
• Torque capacity: Maximum specified shaft torque of 690 Nm.
• Maximum shaft speed: 5,000 RPM.
• Variable-length CV shaft: Length of 155 ± 25 mm.
• Vibration isolation: Hydradrive construction helps reduce the transmission of noise and vibration through the propulsion system.
• Gearbox adapter: Included as part of the complete drive kit.
• Three shaft sizes: Suitable for 30, 35 and 40 mm propeller shafts.

Propeller Shaft Compatibility

Thrust Transmission and Shaft Alignment

The Hydradrive system uses a dedicated thrust bearing to transfer propeller thrust to the vessel's hull. The constant velocity shaft allows torque to be transmitted between the gearbox and propeller shaft while accommodating angular displacement.

The HD-113 is part of the Hydradrive range designed to simplify propulsion shaft alignment and reduce the transmission of vibration through the engine and gearbox installation.

Selection and Installation

Before ordering, the following installation parameters should be confirmed:

• Engine power: Up to approximately 80 HP.
• Maximum shaft torque: 690 Nm.
• Maximum propeller thrust: 10,500 N.
• Propeller shaft diameter: 30, 35 or 40 mm.
• Gearbox configuration: Manufacturer, model and output flange dimensions.
• Installation length: CV shaft length of 155 ± 25 mm.

The correct gearbox adapter and propeller shaft connection should be selected according to the existing propulsion system.
